What is pointing mechanism?
The Pointing Mechanism supports the electric propulsion thrusters in their nominal position during launch, by means of a dedicated hold down and release mechanism and reduces the mechanical loads on the thrusters via dedicated damper elements. Upon its release, the thrusters can be tilted around two axes.
What is antenna pointing?
Home > Technology > Antenna Pointing Method. The antenna alignment refers to the process of adjusting the azimuth, elevation and polarizing angles of antenna to enable the center of beams to point up to the target satellite.
What is antenna pointing error?
The pointing error caused by the structural deformation of large reflector antennas has become the most challenging problem of antenna servo control. In order to solve this problem, accurately estimating the pointing error caused by the structural deformation is the key.
What is a gimbal antenna?
Abstract— For the purposes of antenna or radome measurement, a gimbal may be thought of as a compact, two or three axis antenna positioner with mutually orthogonal, intersecting axes. The unrelenting demand for higher accuracy in positioners of this type is driving innovation in mechanical architecture and design.
Which direction should I point my TV antenna?
When up with the TV antenna, simply point it in the direction of the television transmitter mast. Obviously, this requires the TV transmitter mast to be visible, but if not, it is often possible to align the antenna in the same direction as other local antennas. This may be satisfactory in some instances.
Why does my digital antenna cut in and out?
A: The reason the signal goes in and out is most likely due to “multipath issues.” When a TV signal travels, it bounces off things it hits (such as mountains and high buildings), and those bounces can reach your antenna, confusing your TV’s tuner.
